APPARATUS FOR CHECKING THE WASTE OF WATER..

SPECIEICATION forming part of Letters Patent No. .244,882, dated July 26, 1881.

Application filed March 24, 1881.

To all whom tt may concer n:

Be it known that I, ELLIOTT E. FURNEY,

of the city of St. Louis, in the State of Missouri, have invented certain new and useful' Improvements in Apparatus for Checking the Waste of Water, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings making part of this specification.

My present invention is animproveneut on my patents dated,respectively, September 21, 1880, and January 4:, 1881. The improvements are set forth in th claims.

Figure 1 is an axial section of the apparatus, showing the position of the parts just at'- ter the closing ot' .the .discharge-cock. Fig. 2 is a similar' section, showing the position of parts while the water is flowing, Fig. 3 is a 'diagram in section, showing a modification.

A is `the receiving end of the ap'paratus, connected with the city main, or with some other source ot' supply of water under pressure.

B is the induction-cock, or a cock in the induction-pipe A. The pipe A discharges into the lower end of the case Othroughapassage, c, across which, in Fig. 1, is a bar,`D, carrying a pin, d, whose purpose is to clear the small water-orifice e in the disk-valve E. Iprefer to make the clearing-pin d long enough to eX- tend into' or through the orifiee e when the disk-valve is in its upper position, the pin be-' ing made-to loosely fit the hole e, so that the' water would flow through the lole around the pin. In Fig. 2 is shown a modification in which the clearing-pin d projects from the bottom of the piston H. In this arrangementthe pin would pass into the hole e at eachdescent of the piston. The valve E is raised by the influx of water when the discharge-valve is opened, and descends by gravity when the flow is arrested and the orifice e is kept open by the pin. (See Fig. 1.) The Valve E plays in the lower portion, F', of a vertically-moving cylinder, F, said portion being below the deep circumferential groove G, which groove forms in the cylinder a neck, G', through which the water passes upward to lift the automatic Valve H I, and through which itpasses downward as the pston part of said valve descends. The cylinder F works against the (Model.)

sides of the case G, and hearing so lightly against the sides of the eylinder as to allow its free vertical movements. The valve-piston H works (as a pisten) inside the c\ linder F from the neck G' to the upper end of the cylinder. The piston has in its top a cup, H', which receives a ball-valve, I, detached from the piston H, so that the piston conmences its descent at the moment'the ball-valve reaches its seat K and closes the eductiorpassage L. As the Valve I closes the eduction-passage the excess of pressu're beneath the piston ceases, and the pressire above and below the piston H, cylinder F, and valve E is equalized, causing them to descend, owing to their being of greater specific gravity than water. The ballvalve I does not fit tightly in the piston-cup, 'so that the water has access to the under side of the ball I through an orifice, h, or otherwise, and there is noimpediment to the piston leaving it against its seat.. 'l`heball-valve will remain closed againstits seat as long as the discharge-cock L' in the eduction-pipe L remains open, (or until theinduction-cock B is closed,) and thus prevent the escape of any water, eX- cept the little that passes through the small orifice l, extendingfrom the chamber in case G to the eduction-pipe L abovethe valve; but immediatel y on the closing of the discharge-valve (or the induction-valve) the pressure on the upper side of the ball-valve becomes equal to that below it, and the ball-valve descends from itsseat. The cock or valve L' may be immediately reopened,and the flow will not be again checked by the automatic valve until 'the piston has had time to make its ascent in the cylinder F and carry the ball-valve up to its seat.

.I have shown a ball-Valve, I, as the best form ot' detached valve; but I do not confine myself to this form of valve, but claim any Valve closed by the automatic piston and capable of keeping the eduction-passage closed in the descent of the piston H. The c'losing of the Operatingcock B would act on the automatically-movin g valve apparatus in substantally the same manner as closin g the cock L' in the discharge-pipe.

ends of guide-screws J screwed through the- IOO cease and the Valve apparatus would gra vitate. When there is an Operating-cock, B, in the induction-pipo, a small passage, l', made through the side, bottom, or top of the case C to allow the escape of water from the case, allows the deseent of the valre I, on the closingofthe cock, by removing the exeess of pressure from beneath it, The exit-orifice t' would not be operative for the purpose stated unless the inductionpipe A were closable.

I will now describe the operation of the diskvalve E. This valve, when raised by the influx of water through pipo A, (bythe opening of the cock L' in pipe L, or the cock B in pipe A,) closes against the valVe-seat Gr beneath the neck G' and closcs the o enin 's which lead from the lower part, F', ot' the cylinderchamber into the circumt'erential groove or channel G. When these ports g are closed the water passes through the snal orifice e and through the neck G and causes the piston H to rise. At the same tine the eylinder F is lifted by the pressure of water beneath. The main body ot' water then fiows beneath the edge of the cylinder F, and upward between the cylindcr and case G, then over the upper edge of the cy1inder,and through the ednctiorpipe L, supplying, say, a house or factory.

The ascent of the cylinder F should be limited to prevent its upper edge coming into too close proximity to the top of the case. I provide for this by a collar, F which comes in contact with the lower guide-screws, J, when the cylinder has attained its maximum elevation. (See Fig. 2.) As the water flows through the pipe L the piston His constantly rising in the eylinder F until the automatic valve I reaches its seat K, (unless the cock B or L' is closed. before that time.) When the valve I reaches its seat the flow ot' water is substantially stopped by it, and no more water will flow until the cock has been again closed. On

the closing ot' the cock the valve leaves its seat and another quantity of water can be drawn. When the discharge-pipe L is closed by the valve I the diskw'alve E first drops, opening the ports g, then the cylindcr F descends, closing the passage beneath its edge. As the piston H descends the water beneath the piston cscapes through the neck G' 'and the ports g, and flows up the annular passage F', between the cylinder F and case G, into the top of the cylinder, as shown by arrows in Fig. 1. The piston descends to the neck Gr', but the valve I remains closed against its seat until a (lischarge-cock, L or a cock, B, is opened.

In Fig. 3 is shown a modification in which there is a passage, h', through the bottom ot' the piston H, to allow the water to pass upward through the piston as it leaves the ball- Valve and descends in the cylinder F. In this modification the ball-valve is made of sufficient weight to remain in its cup on the piston while the piston is ascending and keep the passage h' closed.

I claim as my invention- 1. The combiuation of case G,e y1ider F, and automatic Valve, conposed ot' piston H and separable valve I, elosing the eductionpipe L.

2. In an apparatus for checking the waste of water, the combination of an automatic Valve adapted to close the eduction-port of the case, and a passage for the escape ot' water from the case, between the induction valve or cock and the eduction-valve of the case.

3. The combination,with case C and cylinder F, containing an automatic valve adapted to close the ednction-opening of the case, of the disk-Valve E, having orifice e, and closing the ports g, connecting the lower part of the cylinder with the circumferential groove.

4. In an apparatus for checking the waste of water, the combination, with the cylinder F, having seat G of the disk-Valve E, with an orifice, c, and clearingpin d, for the purpose set forth.
